background infections caused by shigella are a major cause of diarrheal disease in the developing and developed countries. the present study was conducted to apply and evaluate arbitrarily primed pcr (ap-pcr) for investigation of genetic relatedness among the strains of shigella sonnei isolated from cases of acute diarrhea in tehran. patients and methods totally, 60 s. sonnei strains isolated f...

A 42-days trial was conducted to study the influence of exogenous enzymes supplementation to sunflower-corn based diet on digestive and performance traits in broilers. There were three treatments (control, Hamecozyme and Rovabio supplemented diets) and three replicates (20 broiler chicks per replicate) per treatment. At the end of the trial, birds fed the enzymes supplemented diets ate more and...

Background: The basic challenge with computed radiography (CR) systems is the large dynamic range which provides an opportunity for radiographers to gradually increase exposure factors and still produce good image quality, a practice that can lead to dose creep. Materials and Methods: The aim of this study was to establish  the entrance skin dose (ESD) values for nine selected examinations in t...

Curcumin (CUR) is a hydrophobic molecule and beneficial antioxidant with known anticancer property. The bioavailability of curcumin is low because of its hydrophobic structure. Mesoporous silica nanoparticles (MSN) loaded by CUR were used as nanocarriers for sustained release of CUR in four different media such as simulated gastric,intestinal, colon and body fluids (SGF, SIF, SCF, and SBF, ...

Let p ∈ [1,∞[ and cp = maxa∈[0,1]((1 − a)ap + a(1 − a)p)1/p. We prove that the known upper bound lindiscp(A) ≤ cp for the Lp linear discrepancy of a totally unimodular matrix A is asymptotically sharp, i.e., sup A lindiscp(A) = cp. We estimate cp = p p+1 ( 1 p+1 )1/p (1+εp) for some εp ∈ [0, 2−p+2], hence cp = 1− ln p p (1+ o(1)). We also show that an improvement for smaller matrices as in the ...
